Background technology
At present, in optical polishing processes, no matter from mechanical grinding theory or the viewpoint of chemically polishing theory, polished die all plays an important role.Polished die can not only carry polishing fluid, ensures that polishing fluid is to the micro mechanics effect of element and chemical action, and the most important thing is the face shape of compensating element, make element reach high accuracy.Therefore, the face shape of face shape on machine component of polished die itself has direct impact.
Conventional polished die has pitch polished die, polyurethane polishing mould etc.Normally large than pitch polished die endless belt by one and the correction-plate that weight is larger of correction for pitch polished die completes.Rely on massive correction-plate to the extruding of pitch polished die, thus change the shape of pitch polished die.Size and the weight of this correction-plate are chosen by experience usually, cannot change once selected, limited to the capability for correcting of polished die, cannot carry out precision correction to the regional area of polished die, the low and judgement of makeover process heavy dependence processing staff of correction efficiency.And for polyurethane polishing mould, usual employing diamond corrector correction polishing die face shape, polished die is made to reach specific shape by removing the grinding of polished die, cannot revise the local error of polished die equally, and the components accuracy that the machining accuracy of element is processed not as good as pitch polished die.For pitch polished die and polyurethane polishing mould, general integral face shape is adapted to good precision by current polished die correcting device, but lacks correction measure effectively for polished die local error.
In the bibliographical information can looked at present and patent, alleviated the report of correction-plate weight as seen by modes such as off-loads, have no report polished die revised by pressurized mode.
Utility model content
For above-mentioned not problem, the utility model provide a kind of can the device of fast processing glass polishing machine polishing die face shape among a small circle.
The utility model solves the technical scheme that its technical problem adopts: polishing die face shape modifier, comprises support column, support, guide rail and drive motors, and guide rail two ends are supported by support column and support and are connected with it; Also comprise translating device, device for exerting and amendment dish; Translating device is fixed on guide rail by chute, and translating device is driven by drive motors; Gag lever post is provided with between translating device and support column; Device for exerting is connected with guide rail through translating device, and device for exerting bottom is connected with amendment dish through pressure transmission bar, is provided with Level-adjusting device between amendment dish and pressure transmission bar, and it is made up of groove and the castor that wherein embeds.
The beneficial effects of the utility model are, device for exerting initiatively can apply pressure to polished die, designs and have employed a kind of reversible amendment dish, and amendment dish variable diameter, pressure controllable system, solve general amendment dish and cannot execute stressed problem in polished die unit are in an active manner, simultaneously, amendment dish solves the uneven problem of polishing die face shape pressure, and reach the amendment face shape of local fixed point, achieve and the high accuracy of polishing die face shape is revised, decrease ring and throw the uncertain factor in processing, effectively can control machine component face shape, promote crudy and the precision of machine component, and improve the efficiency of processing, achieve fixed point amendment face, local shape, avoid polished die rectification plate entirety and press down the poor efficiency and uncertain result that amendment face shape brings.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further illustrated.
See Fig. 1-4, polishing die face shape modifier, comprises support column 10, support 11, guide rail 6 and drive motors 1, and guide rail 6 two ends are supported by support column 10 and support 11 and are connected with it; Also comprise translating device 5, device for exerting 4 and amendment dish 3; Translating device 5 is fixed on guide rail 6 by chute, and translating device 5 is driven by drive motors 1; Gag lever post 2 is provided with between translating device 5 and support column 10; Device for exerting 4 is connected with guide rail 6 through translating device 5, and device for exerting 4 bottom is connected with amendment dish 3 through pressure transmission bar 7, is provided with Level-adjusting device between amendment dish 3 and pressure transmission bar 7, and it is made up of groove 9 and the castor 8 that wherein embeds.
The diameter of amendment dish 3 is less than the width of polished die endless belt.The diameter adjustable of amendment dish 3, initiatively on polished die, can apply pressure in polished die unit are by ballast, have the function of free degree adjustment; And amendment dish 3 can rotate with the rotation of polished die.
Device for exerting 4 is Pneumatic hydraulic device.Amendment dish 3 is carried out to the effect of exerting pressure in vertical direction.Device for exerting 4 is by pressure actuation to amendment dish 3, and device for exerting 4 and amendment dish 3 are fixed on translating device 5, can move with translating device 5 in the scope of guide rail 6.Device for exerting 4 is rotatable, and amendment dish 3 can be driven to rotate.
It is polytetrafluoroethylene (PTFE) that 3 materials are coiled in amendment.Polytetrafluoroethylene (PTFE) is a kind of very wear-resisting and material of extremely difficult distortion, and can not produce pollution in wear process.
The material of guide rail 6 is aluminium section bar.
Translating device 5 is moved by drive motors 1.
Device for exerting 4 is connected with guide rail 6 through translating device 5 with amendment dish 3, and (be fixed on guide rail 6 by chute, translating device 5 keeps fixing in vertical direction to translating device, and can only move diametrically.Guide rail 6 is supported by support column 10, support 11 two ends; Amendment dish 3 has pressure transmission bar 7, castor 8, amendment dish 3 is a concave structure, pressure transmission bar 7 upper end is connected on device for exerting 4, pressure transmission bar 7 lower end is the loose fit with pressure disc 3 inner bottom part, castor 8 is placed in the groove 9 between pressure transmission bar 7 and amendment dish 3, by the effect of castor 8, make amendment dish 3 under the pressure effect of pressure transmission bar 7, certain fluctuating and distortion can be had in vertical direction, thus reaching the effect that polished die is evenly exerted a force, pressure transmission bar 7, castor 8 and amendment dish 3 form the main body of device for exerting 4.
